Abstract

Abstract A drum-like container of fiberboard or similar material supplied in flat knocked-down form and adapted to be set up to serve as a shipping and dispensing container for bulk material. It is provided with a funnel-like dispensing bottom made up of fiberboard segmental wedge-shaped bottom insert sections which are supplied in flat knocked-down form and are adapted to be first set up and then positioned on the bottom of the container in a funnel-like arrangement with a central dispensing opening.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 142 words
A container assembly comprising a tubular body of fiberboard or the like with a bottom structure at its lower end and with side-wall forming panels extending upwardly at the periphery thereof, said bottom structure including support means secured to said side-wall panels; said bottom structure also including a plurality of separate segmental insert sections forming a funnel-like dispensing bottom with a central dispensing opening, each of said separate insert sections comprising an upper material-directing wall having a pair of depending wedge-shaped supporting walls each with a wider end outwardly at one of said side wall panels and extending inwardly to a point spaced from the center of the bottom structure at the dispensing opening, said support walls having lower edges supported by said support means of the bottom to support said material-directing wall so that it inclines downwardly towards said dispensing opening.
Claim 2
Dependent Claim 142 words
A container assembly comprising a tubular body of fiberboard or the like with a bottom structure at its lower end and with side-wall forming panels extending upwardly at the periphery thereof, said bottom structure including support means secured to said side-wall panels; said bottom structure also including a plurality of separate segmental insert sections forming a funnel-like dispensing bottom with a central dispensing opening, each of said separate insert sections comprising an upper material-directing wall having a pair of depending wedge-shaped supporting walls each with a wider end outwardly at one of said side wall panels and extending inwardly to a point spaced from the center of the bottom structure at the dispensing opening, said support walls having lower edges supported by said support means of the bottom to support said material-directing wall so that it inclines downwardly towards said dispensing opening.
Claim 3
Dependent Claim 119 words
A container assembly according to claim 1 in which the body is of multi-sided polygonal drum-like form and includes a preselected number of panels hinged together to form the side walls, said segmental inserts being identical with each other and provided in the same number as said panels and each having an outer support wall depending from said material-directing upper wall and a lower edge supported by the support means of the bottom with the outer wall of each insert being in flat contact with its corresponding side-wall-forming panel, said material-directing wall being of substantially triangular form with a wide end and a narrow end inwardly to thus provide an insert which is substantially wedge-shaped both vertically and horizontally.
Claim 4
Dependent Claim 38 words
A container assembly according to claim 2 in which a flexible bag adapted to be filled is provided within said container body resting on said inserts, said bag having a bottom which can be ruptured through said opening.
Claim 5
Dependent Claim 93 words
A container assembly according to claim 2 in which the bottom structure support means includes a tray-like closure of fiberboard or the like having a flat bottom with a polygonal periphery having upstanding flanges hinged thereto which correspond in number and arrangement to said panels and extend upwardly over corresponding panels to which they are secured, said flat bottom having a displaceable portion located directly below said opening to form a dispensing opening therein, said inserts resting on said flat bottom to provide said opening between their inner ends over said displaceable portion.
Claim 6
Dependent Claim 38 words
A container assembly according to claim 4 in which a pallet is provided on which said flat bottom rests, said pallet having a support part normally supporting said displaceable bottom portion but movable away from that supporting relationship.
Claim 7
Dependent Claim 33 words
A container assembly according to claim 4 in which the container body, tray-like container bottom, and each of the inserts is supplied in flat knocked-down condition and each is set up as indicated.
Claim 8
Dependent Claim 92 words
A container assembly according to claim 6 in which each insert comprises the top material-directing wall of substantially triangular form having a wide outer end and a slightly blunt inner end supported in inclined position by the depending support side walls hinged to the side edges thereof and resting on said flat bottom and by a depending outer wall hinged to the wide outer end thereof and resting on said flat bottom and which has its outer flat surface engaging a flat inner surface of the corresponding panel of the container body.
Claim 9
Dependent Claim 57 words
A container assembly according to claim 7 in which the depending outer wall has locking flap members hinged to each vertical edge thereof and extending inwardly into overlapping relationship with the inner surfaces of the corresponding depending wall members, and aligning inwardly displaceable tabs in the overlapping locking flaps and vertical wall members for locking them together.
Claim 10
Dependent Claim 26 words
A container assembly according to claim 4 in which said displaceable portion is formed in the flat bottom by a circular perforation at the center thereof.
Claim 11
Dependent Claim 21 words
A container assembly according to claim 9 in which slits are extended outwardly from the circular perforation to provide pull-out tabs.
